Re: Dolby Vision now possible through MP4 Mux.

Hi RESET_9999 ,

After generating DV with cm_analyze, is it better to inject the entire new RPU or transfer all its levels to the original RPU?

You mentioned earlier that it’s possible to generate DV for P7 FEL (after prior baking).
What about P5 — is there also a way to generate DV for such movies?

Thanks!

If it's mel, I just inject the new RPU/XML (P8)

P5: I don't know, I never tested.

Are you all mainly looking for the ease of access to the titles? Using these planned obsolescence devices is not a wise decision, but I understand if the concern is mainly the ease of access to the titles, not the device or file properties.
If you're talking about the Kscape I think the idea is to get access to content at the highest quality possible. Unfortunately it seems that device/service does not live up to the marketing hype.
Depends on the content, it seems. Maybe KSCAPE gets bad sources for some files, we don't know.

once you get the webOS 2025 update, PLEX and the G4 native player should support DV MKV too.
In fact, all the TVs that are eligible for webOS 2025 should get DV MKV support.
RESET_9999, do you have more details about the webOS 2025 update? Will it enable profile 7 FEL playback via the Jellyfin or Kodi apps on my G4, meaning that I won't need to use my Ugoos AM6B+ with CoreELEC anymore? I like the Ugoos box, but having this done natively on the TV would be even better!

I tried searching for this, but your post is the only relevant result.

This would be great. I can return my ugoos if this is proven and cited.
Currently it's only playing hdr at this point in the initial set up. I'm concerned about the section highlighted in the attached image as this is where I've stopped in the video setup RESET_9999 made.

Forums are getting updated it seems like, as connection to forums is intermittent and interface look has changed.

This update will allow only P8 and P5 in an MKV container. P7 support on LG TVs was removed in 2020, and the Ugoos will be the best and only P7 player forever.

And I wouldn't use the TVs internal player for DV playback: https://slow.pics/c/IBNzcYOA

Ok, that's what I figured, I don't know if the newer LG TVs even have the decoding hardware required for profile 7. Thanks for clarifying.

What's the name of the colorspace test file?
I'm sorry but I can't find it.
Im thinking about getting the ugoos.
Is the am6 still the go to model, or can I get the newer one like am8 pro or am9?
Also my TV has only HDMI2.0b, will the player-led stuff be supported?

yes am6b+ is the way to go. newer models don't support FEL.
and yes of course, player led is supported.

BTW: MPC-HC on windows have been able to decode DV for some time using LAV filters and MPC Video Renderer. What is the take on this? (especially when using an external display)

Also LAV filters 0.8 released recently claims to support DV metadata natively (but it appears broken for now, based on the latest MPC-HC nightly which includes LAV 0.8 )

@RESET9999

I usually run dovi_scripts (mostly for transferring CMV 4.0 from the web to the Blu-ray version) on the external HDD connected to my PC. Afterward, I unplug it from the PC and plug it into the Ugoos to watch movies. To avoid these plug/unplug steps, I'm thinking about running dovi_scripts on the external HDD connected to the Ugoos via an SMB share from my PC. Is this advisable? I tried it this morning, and it seems quite a bit slower than on the PC.

it will be limited by the ugoos network(1gbps) speed so yeah, it will be much slower than a PC with a SSD or nvme drive.

Yeah, SMB seems to be limited to 30MB/s in both directions (even though it does go higher, seemingly by random, from time to time) You can try NFS for faster network speeds, but it is complicated to set up and not super stable either. I just download stuff directly to the box (using midnight commander) or move my disks to a pc if i need to move huge volumes.

Sorry I meant the external hdd was connected to the ugoos via usb, so dovi_scripts was running on the ugoos (I only operated it from my pc via smb share), so network speed is not relevant here, correct? The ugoos is probably not capable enough to run dovi_scripts, that's why the process took much longer?

Anyway I bought a ugreen usb 3.0 switch, so now I can share the external hdd between my pc and the ugoos. So switch to pc connection when I run dovi scripts, and switch to ugoos connection when I watch movies - just need to press one button to switch, no more plugging/unplugging. So far so good. I can share other devices like mouse and keyboard too. Operating the ugoos with mouse and keyboard feels way better than the remote.
This method is probably cheaper than buying a brand new router that can handle high bitrate 4k hdr plex streaming from my pc to the ugoos, and I don't need to turn the pc on everytime I watch on the ugoos.
